Another overheating question
Ok,
I have a Discovery II 2000, V8, I was driving without any problem, then suddenly my hose broke, I fixed it and I tested it by driving around without any problem, next day I had to change the water pump because it started leaking, at this time the car never overheated, but now after all this the car started overheating as soon i drove 5 or 10 miles.
I was thinking that there is air inside the engine but I have been trying flushing the system without succeed.
Any help I will appreciate

1. Without problem based on observation of the factory gauge, which shows 50% from about 130 - 240F. You can tell there is a problem earlier by using the OBDII port to drive a scanner or Ultra Gauge. See pix below - 2 trucks, 2 different temps, same gauge display.
2. Look at the belt route and verify that you don't have the water pump running bassackward.
3. If you have sounds like water gushing thru pipes under dash you have air or exhaust gas in the coolant. When engine is cold, and off, detach and raise coolant bottle, open the bleeder port on the T, and let it flow out until no more bubbles. Keep coolant bottle from getting empty.
4. If problem keeps up, you could have damaged head gasket or a cracked engine.
5. Be sure fan is mounted correctly, a paper towel should be held against the grille, not blown away.

Yes, when I drive sounds like water under right bottom dash, but I have been googling how to take out the air from the system but with not progress.
PD: Very rare, I found an o-ring inside of coolant bottle, I think came from the cap
Also I am going to make sure the direction of the water pump belt, but I doubt it.
Savannah thank you for your help

Be sure to elevate the expansion tank as high as you can possibly get it. Don't break the small hose that goes to the top of the radiator. Or the nipple it's connected to. Make sure there are no leaks and keep dumping coolant in the tank and let it run out the bleed screw. My 99 took several tries. The 04 worked the first time. Let coolant run out of the bleed screw for a long time coolant will go everywhere but its water soluable it cleans up easy I use kitty litter around an oil catcher don't let tank empty.
Dont let it get hot again Do like S Buzz says get a digital gauge. Could have saved a bunch of money if I had had one last year.
